This study investigated the diversity within the <jats:italic>Maculabatis gerrardi<\/jats:italic> complex, revealing the presence of two distinct geographical lineages, with a potential new species captured off the coast of Mozambique. Molecular analysis showed a significant divergence: COI sequences from Mozambique specimens exhibited over 99% similarity with <jats:italic>M. gerrardi<\/jats:italic> from South Africa but more than 2% divergence from those in the Indo-Pacific. Phylogenetic analysis identified two distinct subclades, suggesting at least two hidden lineages within the genus <jats:italic>Maculabatis<\/jats:italic> and consequently possible new undescribed species within <jats:italic>M. gerrardi<\/jats:italic> complex. These findings emphasize the importance of conducting additional research that integrates both morphological and molecular methods to better understand the group's diversity and evolutionary dynamics, ultimately supporting the development of effective conservation strategies.<\/jats:p>","DOI":"10.1017\/s0025315424000973","type":"journal-article","created":{"date-parts":[[2024,11,27]],"date-time":"2024-11-27T07:40:03Z","timestamp":1732693203000},"source":"Crossref","is-referenced-by-count":1,"title":["A possible new species of the <i>Maculabatis gerrardi<\/i> complex (Dasyatidae: Urogymninae) in the Indian Ocean coast off Southeastern Africa"],"prefix":"10.1017","volume":"104","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7443-4691","authenticated-orcid":false,"given":"Valdemiro","family":"Muhala","sequence":"first","affiliation":[]},{"given":"Auryc\u00e9ia","family":"Guimar\u00e3es-Costa","sequence":"additional","affiliation":[]},{"given":"Isadola Eus\u00e9bio","family":"Macate","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8664-6440","authenticated-orcid":false,"given":"\u00cdtalo","family":"Lutz","sequence":"additional","affiliation":[]},{"given":"Adam Rick","family":"Bessa-Silva","sequence":"additional","affiliation":[]},{"given":"Luan Pinto","family":"Rabelo","sequence":"additional","affiliation":[]},{"given":"Oliver J.","family":"Hasimuna","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8898-0311","authenticated-orcid":false,"given":"Grazielle","family":"Evangelista-Gomes","sequence":"additional","affiliation":[]},{"given":"Marcelo","family":"Vallinoto","sequence":"additional","affiliation":[]},{"given":"Iracilda","family":"Sampaio","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2024,11,27]]},"reference":[{"key":"S0025315424000973_ref25","unstructured":"Sherman, CS , Ali, M , Ali, BA , Bineesh, KK , Derrick, D , Dharmadi, EI , Fahmi, FD , Haque, AB , Jabado, RW , Maung, A , Seyha, L , Spaet, J , Tanay, D , Utzurrum, JAT , Valinassab, T , Vo, VQ and Yuneni, RR (2020) Maculabatis gerrardi.
